INVESTIGATION OF RESIDUAL STRESSES ARISING DURING INCREMENTAL SHAPING

In this article, studies have been carried out to determine the magnitude of residual stresses arising during incremental shaping of a truncated cone, depending on the angle of inclination of its formative. To assess the residual stresses the method of cutting rings was used, according to the results of which it was found that the rings, cut out along the height, manufactured conical parts, when cutting are closed. This indicates the formation of compressive circumferential stresses during incremental shaping. There is also an insignificant axial displacement of the ring ends after cutting rings, which indicates the presence of axial residual stresses, the value of which is negligibly small compared to the value of circumferential stresses. As the degree of deformation increases during incremental shaping (increasing the taper angle), the magnitude of residual stresses decreases.
